IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Leiters Patent No. 149,955, dated April 21, 1874; application tiled September 6, 1873.

To all whom it may concern:

Be it known that I, GEORGE F. SARLES, of Bedford Station, in the county of Vestchester and State of New York, have invented a new and Improved Mosquito Net Attachment to Windows, 85e., of which the following is a specication:

My invention consists of an arrangement of the sash in the window, so that the net can be used at the top or bottom of the window, and shifted from one to the other without interfering with the sash.

Figure lis a front elevation ot' a window with my improved mosquito-net attachment, somey parts being sectioned, to show the ar rangement ot' the ribs on which. the sash is arranged. Fig. 2 is a sectional elevation of Fig. l on the line a: w. Fig. 3 is a horizontal section of Fig. l, taken on the line y y.

Similar letters of reference indicate corre-- spending parts.

The sash A for the net B is composed of two frames, a and b, fitted together in the plane of the net, 011e of said frames, say a, being provided with a tongue, c, which its in a corresponding groove, d, to fasten the net by binding or wedgin g it in between them, as shown, the two parts of the frame being fastened together by nails or screws.

In making this tongue and groove, I propose to iit them so that they will ttogether snugly without the net between them, so that the netwill be securely bound when confined by them, to prevent it from drawing out. lt is important that the groove and rib be formed on right angles, or nearly so, for securing the net to the best advantage.

To fasten the frame A in the window, I make ribs or tongues D on the inside bead E for the frame to run on, which I provide with a groove, F, in two sides corresponding to the ribs'. One rib extends to the top ofthe window as close as the frame can run to the lower window-sash, but the other extends only to the middle, as shown at G,'Figs. l and 2, to allow of putting the net-frame in and taking it out. Also for holding the net-frame up to the top of the window when the upper sash is opened, for which purpose the net-frame is shifted against the upper cross-piece of the lower sash alittle after being raised above the top of the rib to catch the lower corner ot' the net-frame on it, as shown in Fig. 2, for which a little play is provided at that corner.

Thus it will be seen that the net attachment can be put in and taken out ot' the window, and shifted to the top or bottom, without interfe-ring in any way with the window-sash, making it much more desirable than the common arrangement of putting the net-frame in place of one ofthe sash-frames, in which case the window cannot be closed without taking out the net and putting in the sash.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The net-frame fitted on a long` rib, D, at one side and a short one on the other, said ribs being applied to the inside stops or beads E, substantially as specified.
